Honestly the path I see (am guessing) for them is foreigners yeah. I know a few who have foreigner/tourists as their bread and butter so to speak.
But RD could definitely fail in Osaka with you on that. They delayed opening 2-3 times and have next to no one on the roster- and two are visitors from Shinjuku...
But even the places I went to in 2024 that waived Gaijin tax want more than RD for less now, 10,000+ Gaijin tax on a 16,000 meeting (or 15,000) is painful.
But then again tourists will probably happily pay that too
